Flotation Machine
A typical flotation bank comprises a number of such machines in series, "cell-to-cell" machines being separated by s between each impeller, or individual (isolated) tank cells. Historically, "open-" or "free-flow" (hog trough-type) machines allowed virtually unrestricted flow of slurry down a bank.

Flotation
The Inspiration Copper Co. uses flotation as the prime process, and its 800 tons per section is treated by 24 roughing-cells and 4 cleaners. In this case the cells are run in series, the primary cells treating the original feed and the secondary cells re-treating only the slime from the primary tailing after the sand has been removed.

Revisiting a flotation cell benchmark
The work of Parkes et al (2022) was based on the analysis of a well-mixed batch mechanical cell, considered to be equivalent to the plug flow state that arises for a system of steady-state tanks in series. If the batch system processes one unit of feed in a time t, then, the tanks in series processes N units of feed at the same time. So, how ...

1 Froth Flotation – Fundamental Principles
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
